molecular epidemiology

Molecular epidemiology is a branch of public health that studies how our genes and environmental factors influence the risk of diseases. It looks at biological markers, like DNA changes or proteins, in populations to understand how these factors contribute to health and illness. By combining genetics with traditional epidemiology, researchers can identify causes of diseases, predict who might be at risk, and develop targeted prevention strategies and treatments. This approach ultimately aims to improve public health by informing policies and health practices based on scientific evidence.
